MOLD FOR CONCRETE WINDOW OR DOOR FRAMES AND TRIMS.

Specification of Letters Patent.

Patented Dec. 30, 1919.

Application filed January 13, 1919. Serial No. 270,844.

T 0 all whom it may concern:

Be it known that LROBERT S. Own, a citizen of the United States, [residing at Canton, in the county'of Stark and State of Ohio, have invented new and useful Improvements in Molds for Concrete Window or Door Frames and Trims, of which the following is a specification.

This invention relates to a mold for making'concrete window or door frames and trimsg i p One object of the invention is to provide a mold embodying interchangeableparts capable of being readily and conveniently assembled to produce any desired style of door or window frame with conventional or special insideand outside trims and having any desired surface finish.

A further object of the invention is to provide a mold which is capable of being readily. set up and taken down when re quired, which has its various parts so constructed as'to be easily removed from the form afterthelatterhas set, and which is constructed in such manner as to be capable of being set up and used upon a building in the course of construction without interfering-with the door-ways or windows of the limilding. l l

further object of the invention is to. providea form for door-ways or windows which is capable of carrying withit special trims to'be appliedto the facings of such.

doors or windows, andby the use of which these trims are precluded from becoming broken or injured.

Withthese objects in view, together with otherswhich will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, all as will be described more fully hereinafter, illustrated in the drawings, and particularly pointed out in the claims.

In the drawings:.

Figure 1; is a horizontal sectional view taken through one of the upright portions of a mold for forming a window frame,

Fig. 2is a side elevation of a part of the window frame'mold,

Figs. 3 and 4 are horizontal sectional views taken through ,the uprights at each side of the door frame and illustrating-the molds employed formaking such forms," and Fig. 5 isfla detail view illustrating one of the improved clamping devices.

An important feature of the invention is around the anchoring j the jamb to the'frame.

that the molds are capable of being expanded or contracted to constitute the forms for window or door frames of various sizes, and therefore the molds are made up of interchangeable parts or sections, and are equipped with improved fastening devices for easily and quickly securing the parts firmly together or to permit of dismembering the same. Furthermore, the molds are formed of sections of light weight and capable of being easily handled, and the molds may be assembled in upright position or may be laid flat and left to so remain after the plastic hasbeen poured into the same. In instances where special facings or trims are to be applied to the plastic form, these facings are inserted in the molds before the coarse plastic is applied thereto, and retaining rods of approved construction and assemblage are placed within the molds to hold these facings .or trims in proper position during the molding operation.

In Figs. 1 and2 of the drawings there is illustrated "a mold or form for constructing a window frame, and the mold in this instance comprises side plates 6 formed of thin sheet metal and bent so as to provide a frame of the desired shape or configuration. The sections 6 extend inwardly near one end as at 7, and are provlded with forwardly proJect- 7 ing flanges 8 to retain between them the jamb 9 formed preferably of wood. This jamb is to be securely anchored in the plastic constitutjamb to be securely held to the plastic frame.

The jamb is also provided with inwardly ex tending anchoring bolts 12, having the nuts 13 spaced, thereon, and it will be understood that the plastic after having become set bolts will firmly hold The mold may be provided with a suitable core to, provide a pocket or channel indicated at 14 for the accommodation of the sash weightstobe used in connection with the sliding sashes. This core may be formed of any suitable material and may be applied 'nating in the plane of the wall surfaces.

Each of these inwardly turned or bent flanges is engaged by a plate 17, the latter projecting at one longitudinal edge beyond the plane of the mold side, and these projecting portions are provided at spaced intervals with openings of a size suitable to snugly receive the larger ends of the wedge keys 19. The mold sides are each equipped with an angle member 18 so arranged as to lie against the faces ofv the plates 17, and

these angle members have openings registcring with the openings in the said plates 17 whereby the keys 19 may project therethrough. The keys 19 are provided at a point substantially midway their ends with openings to receive the locking wedges 19. It will be observed that the key at one end is headed as at 20 and'this head engages with one face of plate 16, so that the application of the wedge to the key 19 will cause the said head to firmly bind against the said flange. The sides 6 of the mold are connected by the bars or rods 21, and

. these rods extend through suitable OPBllln-gS brackets.

' in the sides of the walls 6, and the protruding ends of these rods are operated upon by the wedges and firmly bound in the After the mold sides have been placed properly and the rods 21 applied, the wedges 19 are forced into the openings-in the keys 19, and the l'OCls are held against movement and are bound firmly against the bracket portions 17.

The wall mold sections are in a similar manner connected to the plates 23 of the wall molds, the sections having angle brackets 24 thereon to cotiperate with each other in forming a rigid structure. These brackets abut when the wall mold plates are properly assembled, and the application of a key 19 and wedge 19 in the manner above described will cause the brackets 24 to be firmly held together. A tie or binding rod 26 may also be ,used in connection with the last named angle brackets.

In Figs. 3' and 1 I have illustrated the sameprinciple carried out informing the sidemembers of a concrete door frame. In this form of the invention, .the said plate 27 connects the inner ends of the mold sections,sand is to be removed with the form after the plastic has become set. This plate is attached to the forwardly projecting flanges of the mold sides by the bolt 28, and is recessed on its inner surface in such mannor that a stop 29 of plastic will be formed after the plastic hardens. The lock catch 30 is formed of metal and is assembled with the mold sections when the form is set up, and this catch is provided with an anchoring bolt 31 to be embedded in the plastic when the latter is applied to the mold. The plate 30 may be backed with a friable core 32, which may be removed after the plastic sets. After the concrete or other substance h a-rdens, the mold sections will be removed, and the plate 30 will be anchored firmly in the door frame in proper position to receive the lock bolt latch of the door to be used in the frame. The core 32 may be picked out after the concretehas set.

In Fig. at there is illustrated a cross sectional view of the door jamb, and the mold sides and end are identical with those described in connection with the frame mold for the opposite side ofthe door frame. In this instance, however, the hinge plate 33 is secured in the plastic mass, andisanchored the-rein by the bolt 34. The plate 33 carries a barrel or knuckle 35 at its outer end, upon which will be pivoted the door. The bolts 31 and 34: may each be provided with a number of nut as shown to enable the same to be securely embedded in the hardened plastic.

In instances where the door or'window frame is to be provided with a special inside or outside trim, the trim 39is molded, formed or built and is appliedzto the in-- terior of the mold prior to the pouring operation. The trims may be held in proper position by the tying or retainingrods 10,

and these rods also assist in holding the mold sections properly centered prior to and be resorted towithout departing'from the spirit of the claims.

I claim 1. In a mold ofthe class described, plates constituting thesides of the mold,brackets invention as definedby the pins or rods may be upon each plate, rods extending from one plate to the other and into said brackets, and fastening members cooperating with said brackets and rods'for holding the latter in position.
